How to Replace Battery
When the display becomes dim, the battery is at the end of its
useful life. Replace it with a new lithium battery (CR2032) with the
(+) pole upward. After replacing battery, be sure to perform "All
Clear" operation and set the scale and wheel size again, as in the
"Main Unit Preparation".
In Ordinary Display
When you start/stop riding, the unit
automatically starts/stops measuring.
While measuring, the scale symbol "k" or "m" flashes.
All Clear
Operation
• Don't pay too much attention to your computer functions while riding. Keep your eyes
on the road and give due consideration to safe riding.
• Securely attach the magnet, sensor and bracket to your bicycle. Periodically check if
the screws and secure bands have loosened.
• Safely dispose of the old battery. Do not place it within children's reach. If swallowed
by mistake, consult a doctor immediately.
• Do not leave the main unit exposed to direct sunlight. Never disassemble the main unit.
• For cleaning, use neutral detergent on soft cloth, and wipe off with dry cloth. Do not
apply paint thinner, benzine or alcohol, to avoid damages on the surface.
• If there is mud, sand or the like clogged between the button and the body, the move-
ment of the button may be deteriorated. Softly wash away such objects with water.
SPD
Current Speed
0.0(4.0) - 100 km/h
±
1 km/h [0.0(3.0) - 60 mph
±
1] (under 60 km/h)
The data is updated once a second.
When it reaches 60km/h (or 60mph), the decimals are omitted.
ODO
Total Distance (Odometer)
0.0 - 9999.9 km [mile]
±
0.1 km [mile]
Continuously measured until battery wears down.
At 9999.9 km, it returns to zero and counting begins anew.
MX
Maximum Speed
0.0(4.0) - 100 km/h
±
1 km/h [0.0(3.0) - 60 mph
±
1]
Displays the highest recorded speed. When it reaches 60 km/h (or 60
mph), the decimals are omitted. With reset operation, it returns to zero.
DST
Trip Distance
0.00 - 999.99 km[mile]
±
0.01 km[mile]
The trip distance from start to current point is displayed. With reset op-
eration, it returns to zero.
Power Saving Function
When the main unit does not receive a signal, or a button has not been
pressed for about 70 minutes, the power supply is shut down and only
mode mark flashes . By pressing the Main button, or by receiving signal,
this function is released.
Trouble Shooting
No display.
Has the battery in the main unit worn out?
Replace it with a new one.
Incorrect data appears.
Do "All Clear" operation.
Current speed does not appear. (When current speed does not appear, first short-circuit
the contact on the back with metal; if the speed display appears, the main unit is normal
and the problem must be in the bracket or the sensor.)
Is there anything on the contact of the main unit or of the bracket?
Wipe the contact clean.
Is the distance between the sensor and the magnet too far?
Are the marking line of the sensor and the center of magnet aligned?
Adjust the position of the sensor and magnet again.
Is the wire broken?
Replace it with a new one.
Current speed does not appear in wet condition.
Wipe the contacts with dry cloth. Contacts can also be treated with a water repellent
silicon jell from an automotive parts store or hardware store. Do not use industrial
water repellent; it may damage the bracket.
